| Lab 3.3.4.2 Switch management VLANs - Overview Estimated time: 45 min. Objectives: This Lab will focus on your ability to accomplish the following tasks: Console into the switch and check switch characteristics and configuration parameters. View / Configure the IP address and subnet mask for the switch Check workstation network settings to verify compatibility with switch and router settings Use the Management console to check and change VLAN configuration for the switch Telnet to the switch based on VLAN and port location Work with the switch Management Domain Background: In this lab you will work with Virtual Local Area Networks (VLANs). You will console into the switch and view the menu options available to manage VLANs and will check the current VLAN configuration. You will also use Telnet to access the switch and check some settings as well as move your connection from one VLAN to another to determine the affects of the "Management Domain". When managing a switch, the Management Domain is always VLAN 1. The network administrator's workstation must have access to a port in the VLAN 1 Management Domain. All ports are assigned to VLAN 1 by default. Tools / Preparation: Prior to starting the lab, the teacher or lab assistant should have a switch available with the default VLAN settings. A workstation with HyperTerminal should be available to console into the switch and an Ethernet connection should be available to Telnet into the switch. Since there may be only one switch available, the instructor should demonstrate this lab at a minimum and students should work in larger teams to get hands on. While one team is doing switch labs the others could be doing web-based research on switches at the Cisco web site URLs listed below. Before beginning this lab you should read the Networking Academy Second Year Companion Guide, Chapter 3 - VLANs. You should also review Semester 3 On-line Lesson 3. Following is a list of equipment required: Two Windows PC workstations w/ HyperTerminal installed (configured for console connection to switch) Cisco Switch (19xx or 28xx model) Console Cable (roll-over) and DB-9/RJ45 adapter or DB-9 null modem cable. CAT 5 Ethernet Cable from the workstation to a switch Ethernet port Web Site Resources: LAN Switching basics General information on all Cisco products - (Scroll down to chapter 16 - Switches) 1900 / 2820 series Ethernet switches 2900 series Fast Ethernet switches 3500 series Gigabit Ethernet switches Cisco switch clustering technology Virtual LANs for 1900/2820 Switches Notes: Step 1. Console into the LAN switch. Console into the switch by attaching the workstation serial port to the switch console port with a rollover cable and answer the following questions. Use the switch attached to Router Lab-A or other another one (Note: Answers will vary depending on switch model number) 1. What is the model number of the switch? 2. Does this switch have Standard Edition or Enterprise Edition software? 3. What is the Firmware version of the switch? 4. What option on the menu is used to set IP address of the switch? 5. What option on the switch menu is used to create or modify VLANS? Step 2. Assign an IP address to the switch. 6. Assign an IP address and subnet mask to the switch. Be sure to use an IP address and subnet mask that are compatible with the network or subnet the switch is currently on. If the switch is connected to Router Lab-A, Interface E1 as shown in the standard lab setup diagram, then assign a compatible IP address and subnet mask to the switch. IP Address: ____________________ Subnet Mask: _____________________ Step 3. Check VLAN configuration options. 7. Select VLAN option from the menu. How many VLANS can be configured with this switch? 8. Verify that all ports are assigned to VLAN 1. List the ports that are currently assigned to VLAN1. 9. List the first three "Actions" that are available on the VLAN submenu. Which menu option is used to move a port to a different VLAN?
Menu Opt. | VLAN Menu Option Description | Sub-menu options (list two or more)
Step 4. Attach a workstation and Telnet to the switch. Connect the workstation to the switch with a straight-through CAT5 Ethernet cable using port 12 on the switch. Verify that the workstation has IP address, Subnet Mask and Default Gateway settings that are compatible with the switch and router. Telnet to the switch from the workstation DOS prompt. 10. What command did you use? 11. Were you able to Telnet to the switch? 12. Move port 12 to VLAN 2. What happened to the Telnet session? 12. With the workstation attached to port 12 on VLAN 2 can you still manage the switch? 14. Why or Why not? 15. Move your workstation connection to port 11 on the switch. Can you Telnet to the switch now? 16. Why or why not? 17. Explain why your Telnet session failed when you move your workstation from port 11 (VLAN 1) to port 12 (VLAN 2) on the switch.
